Technical Field

The utility model belongs to the technical field of conveyor belts, and particularly relates to a tearing-proof protection device.

Background

The conveyor belt is a carrier medium conveyor belt system (commonly referred to simply as a belt conveyor). One type of belt conveyor system is one of many types. Belt conveyor systems consist of two or more transfer pulleys (sometimes referred to as drums) with a closed loop of carrier medium (belt) rotating around them. One or both of the belt pulleys is driven to move the belt and the material on the belt forward. The powered transmission pulleys are referred to as drive transmission pulleys, while the unpowered transmission pulleys are referred to as idler pulleys. Belt conveyors have two main industrial categories; those in general material handling, such as moving boxes within factories and bulk material handling, such as handling for transporting large amounts of resources and agricultural materials, such as grains, salt, coal, ore, sand, overburden, etc.

For example, chinese patent publication No. CN212768243U discloses a tear-proof device, which solves the problem that it is difficult to accurately position the distance between the mechanical sensor and the upper conveyor belt when the tear-proof device of the existing conveyor belt machine is installed.
